An electron in a cathode ray tube (CRT) accelerates from 2.00X104m/s to 6.00X106m/s over 1.50 cm. (a) How long does the electron take to travel this 1.50 cm? (b) What is its acceleration?

A space probe on the surface of Mars sends a radio signal back to the Earth, a distance of 7.96 ✕ 107 km. Radio waves travel at the speed of light (3.00 ✕ 108 m/s). How many seconds does it take for the signal to reach the Earth?

A particle is moving in three dimensions and its position vector is given by; r→(t)=(1.6t^2+3.7t)i+(3.7t−1.4)j+(4.6t^3+3.8t)k where r is in meters and ?t is in seconds. Determine the magnitude of the average acceleration between t=0s and t=2s. Express your answer in units of m/s2 using one decimal place.

Part (a)  What is the velocity, in meters per second, of the particle at the time t1 = 3.0 s?  v(t) = ______ m/s Part (b)  What is the velocity, in meters per second, of the particle when it is at the origin (x = 0) at time t0 > 0? v(t0) = ______ m/s
